HOSE-COUPLING.

SPECIFICATION forming part of Letters Patent N o. 763,236, dated June21, 1904. Application filed Deeember 7, 1903. Serial No. 184,085. (Nomodel.)

To all whom it may concern:

Be it known that I, JOHN WINKLER, a subject of the Emperor ofAustria-Hungary, residing at McKeesport, in the county of Allegheny andState of Pennsylvania, have invented certain new and useful Improvementsin Hose-Couplers, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to certain new and useful improvements inhose-couplers; and the primary object of the invention is to provide acoupler in which the members may be easily and quickly connected and aseasily and as quickly disconnected when desired.

Briefly described, the invention comprises a male and a female couplingmember, the female member having an interior annular seat and providedon opposite sides with exterior bayonet-shaped recesses. The male memberhas a slitted nipple extension which is adapted to be sprung intoposition in the seat in the end of the female section or member and isalso provided with bayonet-shaped lugs that are adapted to engage in thebayonet-shaped recesses in the exterior of the female member and lockthe two sections together.

The above construction as outlined briefly will be hereinafter describedin detail and then specifically claimed, and in describing the inventionin detail reference will be had to the accompanying drawings, forming apart of this application, and wherein like numerals of reference will beemployed for indicating like parts throughout the different views of thedrawings, in which Figure 1 is a side elevation of a couplingconstructed in accordance with my invention. Fig. 2 is a centrallongitudinal sectional view thereof. Fig. 3 is a transverse verticalsectional view, and Fig. 4 is an end view, of the female member of thecoupling.

To construct a coupling in accordance with my invention, 1 provide afemale member 1 and a male member 2, each of which may be provided withthe exterior corrugations adjacent their outer ends to receive the hose.The female member is provided in its engaging end with an interiorannular seat 3, which .increases the bore in the female member at theengaging end of the latter. This seat 3 adjacent its ends has beveledwalls 4, the forming of the seat producing a shoulder 5, against whichthe extension carried by the male member is adapted to abut when themembers are in coupled position. On opposite sides of its exterior thefemale member is provided with recesses 6 of L-shape or bayonet-shapeform, the wide leg or portion of these recesses extending longitudinallyof the member and the shorter leg or portion 7 being somewhat wider atits registry with the main portion of the recess than at its closed end,this leg or portion 7 of the recess extending transversely of themember.

The male member 2 of the coupling carries a nipple extension 8, providedwith slits 9, extending from its outer or free end to a point adjacentits integral end, whereby to impart suflicient spring to the nipple topermit of its being compressed and forced into the socket or seat 3,provided therefor in the engaging end of the female section. This nippleextension 8 has its central portion bulged outwardly, whereby its endsconstitute beveled seats 10, adapted to fit neatly with the beveledseats 4 4 of the female section when the members are in the coupledposition, as seen in Fig. 2. The male member is provided on its exterioropposite sides with L shaped or bayonetshaped lugs, the longer legs 11of which lie in the recesses 6 and the tapered legs 12 of which engagein the recesses 7. It is to be noted that the open ends of the portionsor legs 6 of the recesses are of a width sufficient to receive the freeends of the L-shaped lugs therein, and after the nipple extension hasbeen forced into its seat or socket the one member or the other is givena partial revolution, so as to move legs 12 into recesses 7 and lock themembers in engaged position.

It is to be observed that the coupling is easily and quickly effectedand an absolutely tight joint is made without the use of threads on themembers.

While 1 have herein shown and described in detail a practical embodimentof my invention, yet it will be observed in the practice of the samethat various changes may be made in the details of construction withoutdeparting from the general spirit of the invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a hose-coupling the combination of two members, one member beingformed with a bayonet-slot cut out of its peripheral surface and beingalso formed with an internal recess constituting an enlargement of itsbore, said recess extending to the end of the member and havinginwardly-inclined ends, the other member being formed with an integrallug adapt- JOHN WINKLER;
